Some users reported crashes with AMD cards when creating or loading a galaxy using AMD driver version 23.12.1 or 24.1.1. We have implemented a workaround that hopefully addresses this issue. If you had this issue, please report in the comments if this patch fixes the issue for you (on driver 24.1.1). If the problem still exists we recommend a downgrade to driver 23.11.1.
Some background on the status of this issue, by one of our devs:
"This problem is particularly difficult to debug. Originally none of our office PCs with AMD cards were affected. However, we managed to build a PC where we can reproduce the issue, but even with this PC, the crash doesn't happen reliably.
On a technical level, the crash happens in a thread run by the AMD driver in the Avorion process. This should not be possible unless there is a bug in the driver. For those who don't know: a driver *must not crash*. We have verified multiple times that our code is correct and doesn't raise any errors. We've contacted AMD multiple times over different channels but have not received a helpful answer, yet.
Warning, technical: To analyze the cause, we tried to disable various parts of the engine. When the crash disappeared we always had to test many times, as it wasn't 100% reliable. No crashes a few times in a row can just be plain (bad?) luck and lead down the wrong path. We finally found different, independent functions we could disable, that individually stopped the crash. None of them look like they made sense as a cause for a crash. Just leaving them disabled was no option either, we had to find a solution without impacting the content of the game. We settled on restructuring a small part of preparatory texture work so we give the driver less work while loading the game, and forced the driver to complete some of its work on our schedule instead of its own."
We're very sorry for the inconvenience. We hope that the workaround we've screwed into our engine fixes the issue for you fine AMD folks, and we hope we can remove it once the driver crash was fixed by AMD.
